o.o yea i have a theory....i dont think its a good theory, but its a theory nontheless and i'll tell u since its ur comic and ur obviously curious XD
so, i think that for some reason.. i guess maybe Abby's dad sexually abused her as an output for her mother being dead..? maybe thinking of her as her mother..if that makes any sense @_@ and i guess he physically and maybe mentally abused her as well, and so she couldn't take it and costantly tried to cut herself..? i guess on the last page she was gonna end her life for sure but found hope in Kim maybe..? idk..its not a good theory, but that's what i came up with since you were only going so far with info ^^;;
OMG this is a long comment -_-;;
lol anyway...on to this page... bet she's gonna hang up o.o

edit: this is just a random slow moment but i just noticed that on the sides of this webpage thing it has Noemi and Daniel instead of Chris and Jimmy XD
